(Swift, macOS, storyboards)
//I have a JSON in a URL. Simplified it is something like this:
{
"id": 1,
"name": "Leanne Graham",
"with-hyphen": 123
}
//Outside the class ViewController:
struct User: Codable {
let id: Int
let name: String
let with: Int
}
//In the class ViewController:
@IBAction func getJson(_ sender: NSButton) {
let url = URL(string: "https://example.com")!
URLSession.shared.dataTask(with: url) { data, _, _ in
if let data = data {
let result = try? JSONDecoder().decode(User.self, from: data)
//let result2 = result!.name //it works
//let result3 = result!.with-hyphen //it does not work
//print (result3)
}
}.resume()
}
I can safe in a let the regular "id" and "name" but I do not know how to deal with the keys with hyphens, in the example: "with-hyphen"
You cannot have hyphens in names.
The best is to use CodingKeys.
struct User: Codable {
let id: Int
let name: String
let withHyphen: Int
enum CodingKeys : String, CodingKey {
case id = "id"
case name = "name"
case withHyphen = "with-hyphen"
}
}
Then call:
let result2 = result!.name
let result3 = result!.withHyphen
Avoid using with, it is a reserved word.
